I love your icons! I'm using them on my Gnome desktop
But i've a little question to you. I'm changing system graphics and menu icons on my mobile phone (Siemens ME75, almost the same OS as C75), because i hate them. And i wonder if i can use your icons (Dropline Neu! 0.6 PR3 - latest available i found on your blog). I want them only for my private use.
Also, i have to modify some of them (for example: remove "light" on addres book, remove warning on battery, make green "OK" status icon, add some emblems to "e-mail" icon [ie. SMS not send alert] and so on), but i couldn't find any license info on your blog...
If you agree, and if it will success, i'll upload screenshots of my phone on dA
